A network of private Japanese citizens, calling themselves Green Fund, are due to begin operating their fourth wind project this month. Installation of two Vestas 1.65 MW machines is due to be completed shortly near Ishikari city in the main northern island of Hokkaido. While 25% of the cost of the ´600 million project comes from government subsidies, the remainder results from the sale of 1900 shares to the individuals who make up Green Fund. The electricity generated will be sold to the local utility under a 15 year contract. The return on investment is calculated at 2.4%. The three other Green Fund projects already operating are a 1 MW Bonus wind turbine in the town of Hamatombetsu, Hokkaido Prefecture, a 1.2 MW GE Energy machine in Ajigasawa, Aomori-Prefecture, and a 1.5 MW Repower turbine in Tenno, in the Akita Prefecture.
